SAFETY INSTRUCTIONSGeneral Carefully read the installation and operation instructions prior to installation or maintenance. While working with the filter all conventional safety instructions should be observed in order to avoid dangerto the workers, the public or to property in the vicinity. Note that the filter enters into a self-cleaning cycle automatically, without warning. No changes or modifications to the equipment are permitted without written consent provided by themanufacturer or by its representative, on the manufacturer’s behalf.Operation, Control and Maintenance Do not open any cover bolts or fittings unless pressure in the filter has been released. Keep the work area around the filter clean and dry. Always open and close valves gradually. Manual cleaning of the filter element using high water pressure or steam should be performed in accordance with thecleaning system instructions. Manual cleaning of filter element using acid or other chemical agents should be performed in accordance with therelevant material safety instructions.Use of Lifting Equipment While using lifting equipment, make sure that the filter or the lifted part is chained securely and in a safe manner. Avoid working below lifted equipment. Wear a safety helmet while using lifting equipment. Attach the lifting equipment to the lifting eyes only.6

INTRODUCTIONGeneral DescriptionThe MG110 is a sophisticated, yet easy-to-operate automatic filter, with a self-cleaning mechanism driven by a hydraulicturbine. It is designed to work with various types of screens in filtration degrees from 800 to 50 micron, and is available in10" inlet/outlet diameter.The MG110 filter is configured to meet your specific needs according to flow rates and water quality. The filter can beinstalled as a stand-alone unit for low flow rates, or assembled in a group on a manifold when high flow rates and/or alarge screen area are required. The filters are delivered fully assembled, requiring simple connections to the inlet andoutlet, and to the drain.Basic Filter OperationWater enters the filter from the inlet pipe, and passes through a coarse screen, which protects the automatic cleaningmechanism from any large particles or debris. The coarse screen is not cleaned automatically, and should not accumulatelarge quantities of solids. The water then flows through a fine screen which filters out the smaller particles. Water that haspassed through the fine screen is clean and passes into the outlet pipe. Particles of dirt accumulate on the fine screen andform a ―filtration cake,‖ which starts to restrict water flow. As the restriction, or clogging, increases, the pressure in theoutlet pipe becomes lower than in the inlet pipe. When the pressure differential reaches a pre-set value, a self-cleaningcycle is initiated. The self-cleaning cycle takes approximately 45 seconds and does not interrupt the flow of water throughthe filter.How the Self-Cleaning Cycle WorksAt a preset pressure differential (0.5 bar —7 psi), which is detected by a pressure differential switch, the flushing controlleroperates pulse solenoids which allow water to flow to the relay valves, which then activate the hydraulic pistons and opena valve to the rotor chamber (See Figures 2 and 3). The water from the rotor chamber flows out the drain. The pressure inthe rotor chamber drops, releasing a strong flushing stream that flows through the filter.This drop in pressure and corresponding release of the backflush stream create a suction effect at the nozzle inlets. Thiseffect actuates spot cleaning directly in front of the openings of each nozzle at the inner side of the fine screen. The waterand particles passing through the hydraulic rotor cause the suction scanner to rotate, and the piston moves in an axialdirection to the opposite end of the filter.The combination of rotational and axial movement of the suction scanner assembly ensures that the nozzles sweep theentire inner side of the fine screen in a spiral pattern.When the first stroke is completed, the flushing valve closes and after a short interval the flushing controller activates thesecond backflush stroke. The suction scanner assembly spins, moving with the piston in the opposite direction andreturning to its original position.This self-cleaning process takes about 45 seconds, depending on the operating pressure.It is essential that there be at least 2 bar pressure at the inlet to the filter for proper cleaning to take place during flushing.The flushing controller may be operated by pressure differential, manual activation, or by timer.7

How the Flushing Controller WorksThe flushing controller is operated by 12 VDC. It receives a signal from the Differential Pressure Switch when the pressuredifferential reaches the preset value (0.5 Bar, 7 PSI). The flushing controller then sends a 12 VDC pulse to the PulseSolenoid, which provides hydraulic pressure to the Hydraulic Relay which actuates the piston. Where there are severalganged filters, there are solenoids to each relay valve and piston and they are activated in turn, not simultaneously, inorder to maintain inlet pressure and avoid large pressure drops. The unit can also control a downstream valve, which maybe closed while flushing to increase pressure. An optional electronic counter can keep track of the number of flushingcycles.Parameters which may be set include: Mode of operation: Manual, Differential Pressure (DP) only, DP with time override Flushing cycle Flushing time Dwell Time DP response delay time Number of consecutive flushing cycles by DP, to be considered a faultHow the Hydraulic Relay WorksThe hydraulic relay valve, when not actuated by hydraulic pressure from the pulse solenoid, allows pressure to pass to thehydraulic piston, extending it, and holding the suction scanner away from filter lid. When the hydraulic relay is actuated,pressure to the piston is shut off and the water in the piston flows out to the drain. When the piston is no longer underpressure the suction scanner pushes the piston away from the filter lid.FILTER LIDCOMMANDPRESSUREDRAINDRAINPISTONFigure 5: Hydraulic Relay9

INSTALLATIONDesign Recommendations‣ The inlet and outlet pipes must be the same or a larger diameter than the inlet and outlet diameters of the filter.‣ The upstream pressure source should not drop below 30 psi (2 bar) during the rinse cycle. If this cannot be ensured,consult the manufacturer.‣ If a prolonged pipeline fill time causes a temporary high flow and low pressure situation, it recommended that youinstall a pressure sustaining valve downstream of the filter. The pressure sustaining valve will ensure a controlled fillupof the line.‣ If continued water delivery is essential even during ―down time‖ maintenance periods, it recommended that a manualor automatic by-pass be installed, and that isolating valves be installed up and downstream of each filter unit forisolation purposes.‣ Shut off valves must be installed in the inlet and outlet lines to enable maintenance.‣ A non-return valve should be installed where water hammer or back flow may be a problem.‣ The filter must be installed in the direction of flow indicated by the arrow on the filter body.‣ Secure the drain pipe so that there is no movement during flushing.‣ The highest point of the drain pipe should be no more than one half meter above the filter.‣ The drain pipe must allow free flow and be free of restrictions.Preparations for Installation‣ Ensure suitable lighting at the area of the filter to enable good visibility and safe maintenance.‣ Arrange suitable platforms and safety barriers to enable easy, safe access to the filter.‣ Allow a convenient approach and enough space for dismantling and maintenance.Installation Instructions‣ Ensure the direction of flow is according to arrows marked on the filter housing‣ Install a drain valve in place of one of the pipe plugs in the inlet or outlet pipe on the installation manifold.Important!‣ Prevent static back pressure or reverse flow through the filter.‣ Install a manual or a hydraulic valve downstream of the filter.‣ The filter may enter flushing mode automatically, without warning.10

A. General DescriptionArkal’s DC Controller is an electrical/electronic device designed for controlling the flushing process of various types ofautomatic filters.The controller is capable of controlling up to 6 12VDC Latch Solenoids which enables it to operate several types of filtrationsites such as:• Automatic screen filters batteries, up to 6 units each.• Gravel media filters batteries, up to 6 units each.• Automatic disc filters batteries, up to 6 units each.• One Arkal TAF Electronic Filter.Unlimited number of controllers can be chained together in order to control large filtration sites.The flushing process can be triggered by:• Differential Pressure (DP) signal• Time parameter• Manual Start command• Remote Start signal (By receiving an End of Cycle input from a chained controller)Beside the filters outputs and the DP input the controller is also capable of controlling the following additional functions:• Main Valve (replaces one of the 6 maximum filter units outputs)• Delay Valve (replaces one of the 6 maximum filter units outputs)• Dry Contact Auxiliary Output that works in parallel with the main/delay valves• Alarm output• End of Cycle output• Pause inputThe controller's enclosure is made of Polycarbonate and is designed for outdoor use (IP 65).B. Flushing MethodsThis chapter lists and describes the sequence of operation of the major flushing methods possible to operateusing Arkal Flushing Controller:1. Controlling Arkal TAF Electronic filter:1.1 A single TAF filter:Starting the flushing cycle:• DP signal: Once a signal from the DP switch is received the controller starts to count down the DP delaytime (see screen number 7). If the signal remains present till the end of the count down a flushing cycle starts.• Time parameter: By the end of each flushing cycle the controller starts to count down the Time betweenFlushes Parameter (see screen number 7). Once this parameter is counted down to zero a flushing cycle starts.Please note that if a flushing cycle is started by a different trigger (i.e. DP signal) the controller re-set thecount down of the time between flushes parameter and starts to count it again.• Manual Start: The user initiates a flushing cycle by pressing Enter in the ―For Manual Flush Press ‖screen (see screen number 3).• Remote start signal: Works the same as a regular DP signal.17

2. Controlling a single automatic screen or gravel media filter:2.1 A single screen or gravel media filter:Starting the flushing cycle:• The same as in ―A single TAF filter‖ above.The flushing cycle:• The same as in ―A single TAF filter‖ above.2.2 A single screen or gravel media filter with a Main Valve:Starting the flushing cycle:• The same as in ―A single TAF filter‖ above.The flushing cycle:• The same as in ―TAF filter with downstream valve‖ above.3. Controlling a battery of automatic screen or gravel media filters:A battery of automatic screen or gravel media filters consists of 2-6 filters installed in parallel and serves thesame water system, where one Arkal Flushing Controller controls the system.This arrangement allows a sequential flushing process where only one filter flushes at a time and the filters areflushed one after the other.Please note: The maximal number of filters in a battery controlled by a single controller is 6 where neitherMain Valve nor Delay Valve are configured, 5 where a Main Valve or a Delay Valve is configured and 4 whereboth Main and Delay valves are configured.3.1 A battery of screen or gravel media filters without a Main valve:Starting the flushing cycle:• The same as in ―A single TAF filter‖ above.The flushing cycle:• Solenoid valve number 1 is switched on, the flushing of the first filter of the battery starts and thecontroller starts to count down the Flushing Time parameter (see screen number 5). Once this parameter iscounted down to zero the solenoid of the first filter is switched off and the process moves to the nextstage.• The controller counts down the ―Between Filters Delay‖ parameter (see screen number 5) and once thiscount reaches zero the controller switches on the solenoid of the second filter of the battery and startsto count down again the Flushing Time parameter. Once the flushing process of the second filter isfinished the controller counts again the delay between filters and starts the flushing of the next filter.This process continues till the last filter is flushed and the flushing cycle is ended.19

3.2 A battery of screen or gravel media filters with a Main Valve:Starting the flushing cycle:• The same as in ―A single TAF filter‖ above.The flushing cycle:• The Main Valve solenoid is switched on and closes the battery’s Main Valve. The controller countsdown the ―Delay Main Valve Close‖ parameter (see screen number 8). Once this count reaches zero theprocess moves to the next stage.• Solenoid valve number 1 is switched on, the flushing of the first filter of the battery starts and thecontroller starts to count down the Flushing Time parameter (see screen number 5). Once this parameter iscounted down to zero the solenoid of the first filter is switched off and the process moves to the nextstage.• The controller counts down the ―Between Filters Delay‖ parameter (see screen number 5) and once thiscount reaches zero the controller switches on the solenoid of the second filter of the battery and startsto count down again the Flushing Time parameter. Once the flushing process of the second filter isfinished the controller counts again the delay between filters and starts the flushing of the next filter.This process continues till the last filter is flushed and its solenoid is switched off, then the processmoves to the next stage.• The controller counts down the ―Delay Main Valve Open‖ parameter (see screen number 8). Once thiscount reaches zero the Main Valve solenoid is switched off causing the Main Valve to reopen and theflushing cycle ends.20

G. MonitoringDuring the regular operation of the controller it is possible to:• Monitor the current status of the controller• Read information on past activities of the system• Perform manual operation and intervene in the flushing process• Read and monitor the voltage of the controllers batteryThe layout of the screens involved in the controller’s Monitoring can be found on page 10 of this manual. Thefollowing table describes each one of the controller’s Monitoring screens and it contains three columns.• The first column shows the screen number as appears at the upper left corner of the screen drawing inthe layout diagram on page 10 of this manual.• The second column shows the default setting of the screen.• The third column explains the controller-task controlled by this screen.Number Screen Description2310Status:B.FlushinTime: 4:23:35For manual flushPress Flushing counter11This screen shows the current status of the controller.The upper line: - shows the current status, The possible messages are:• Flushing (the flushing filter number is also displayed)• Between filters (counting the delay between filters)• Between flushing cycles (counting the time to the next flushing cycle)• Delay (counting the D.P. delay)• Fault (the controller is at D.P. fault)The lower line: - shows the countdown of the time related to the upperline message, for example:• When the controller is between flushing cycles this line shows thetime left to the next flushing cycle.• When filter number 1 is flushing this line shows the time left for thisfilter to flush.In this screen the user can manually start and stop a flushing cycle.• Press Enter to immediately initiate a flushing cycle.

12Battery6.14 VoltThis screen shows the voltage of the controller’s battery.The minimum operational level is 4.7 VH. Handling faultsArkal’s flushing controller can detect and respond to filter clogs. This is done by monitoring the status of the D.P.signal. The user can configure the controller’s response through the following two screens:Number Screen Description617Flu Til Fault: 3Delay: 10DP Input: *yesDisc filter: *noIf by the end of a flushing cycle the D.P signal remains ON thecontroller counts down the delay entered in this screen (in seconds),and if by the end of this delay the D.P. is still ON a new flushing cyclestarts. In case the D.P. remains permanently ON the delay is countedagain and this process repeats till the ―maximum number of flushingcycles till fault‖ entered at this screen is exceeded.Once this happens the controller enters into a Fault Status asdescribed below this table.Please note that if zero is entered at the ―maximum flushing cycles tillfault‖, the controller never enters to ―D.P. Fault Status‖ and continuesto initiate new flushing cycles constantly whenever the D.P. signalremains ON.If the lower line parameter of this screen is set to ―Disc filter *yes‖ thecontroller immediately enters to ―D.P. Fault Status‖ whenever the D.P.signal remains ON at the end of the first flushing cycle.When the controller enters to D.P. Fault the main status screen (Screen number 2) shows the fault status and time.Status:D.P. FaultTime: 4:23:35A new screen appears to the right of the main status screen (Between screens 2 and 3) displaying the option to resetand release the fault and the controller’s buzzer is activated.To Release D.P.Fault When the controller enters to D.P.

Battery and power levels:In order to prolong the battery life the controller switches off the display screen of the unit once the keyboard isnot used. In such case the operation of the unit continues as usual. Press any key to switch on the displayscreen.The required voltage level for regular operation is 4.7-12 Volts. Once the voltage level drops below 4.7 V thecontroller stops its regular operation, switches on the Alarm and enters into Fault status.I. Technical dataElectrical Connections:The Electrical Connections BoardExternal Power supply6-12 VDC:This connection terminal is used to connect, when available, a 6-12 VDC 500 milliamp external power supplyunit to the controller.Once such external power supply is connected the internal batteries of the controller are used only for a backupand not for the actual operation of the controller.32

Outputs:OUT1-OUT6:These are the terminals for the Two Wire 12V DC Solenoids. If a main valve or a delay valve has beendesignated during the controller’s configuration process, it's solenoid's output will always assigned to OutputNumber 6. For example, if two outputs are defined as filters (OUT1-OUT2), the main valve output will be OUT6.If both main valve and delay valve are defined, Output Number 5 will be the delay valve output and the OutputNumber 6 will be the main valve output.Auxiliary Output (marked on the controller’s terminal strip as Main Valve):This output is opened and closed automatically by the controller in parallel to OUT-6, i.e. this output is activatedwhenever OUT-6 is activated.Alarm:This output is a Dry Contact Relay (a free potential contact); it provides a command pulse to an external alarmdevice. The alarm is activated in two cases:• When a selected number of consecutive flushing cycles have taken place due to continuous differentialpressure input signal, which usually occurs when the filters are clogged.• When the battery voltage is lower than 4.7 VDCEnd of Cycle (End C):This output is a Dry Contact Relay (a free potential contact); at the completion of a flushing cycle it provides acommand pulse connected to the D.P. input of an external controller (slave). This pulse lasts 5 seconds andtakes place after all the other outputs of the flushing process have been activated and de-activated. See―Chaining Arkal Controllers‖ drawing at the end of this chapter.Note: This output in marked as SEO in the AC controller, the functionality is the same and therefore it ispossible to chain AC and DC controllers.Inputs:D.P.:This is the connection to the differential pressure switch.Pause:Connecting these two terminals creates a signal which causes the controller to stop operating until theconnection between these two terminals is disconnected.33

Installing and replacing the batteries:The controller is powered by four D batteries. The unit starts to operate automatically 10 seconds after insertingthe batteries. Alternatively, an external 6-12V DC supply can be connected to the power connection terminal;(Labeled as 6-12 VDC on the terminal board circuit board.)If an external power supply is connected while a set of batteries is installed, the batteries are served as abackup and are not in use as long as the external power supply is connected.In order to install or replace the batteries:• Open the transparent keyboard lid.• Unscrew the 4 screws located in the corners of the keyboard and screen panel.• Remove the panel from the controller housing to get access to the battery compartment.• Insert 4 D type 1.5VDC batteries according to the (+) and (–) marks on the compartment.• Insert the panel and cover the battery compartment.• Re-screw the 4 screws and close the transparent lid.34

Chaining Arkal Controllers:In order to operate a battery of screen or gravel media filters that include a larger number of filters than oneArkal’s Flushing Controller can handle, it is possible to chain few controllers for the job.The D.P. switch that reads the pressure drop across the battery is connected to the first controller of the chain(the Master). The SEQ (or End of Cycle) output of the master controller is connected to the D.P. input of thesecond controller of the chain (the first slave) and this controller SEQ output is connected to the D.P. input ofthe nest. This type of connection can be spanned over as many controllers as needed.When the actual D.P. switch send a signal the master controller starts a flushing cycle. Once this cycle iscompleted the master controller sends a signal through its SEQ output to the second controller to start itsflushing cycle, and so on till the last controller in the chain as illustrated in the following drawing.Master ControllerSlave 1 ControllerSlave N ControllerEnterEnterEnterD.PSEQD.PSEQD.PSEQInputOutputInputOutputInputOutputStandard D.P.Switch36

J. Annex A. – Operating filters that require a Delay ValveIn some cases there is a need to control a Delay Valve together with the filtration system, for example ininstallations where a delay Valve is used for sampling the flushing water.Arkal’s Flushing Controller contains two parameters which allow the user to control a filtration system thatrequires a Delay Valve; these are the ―Delay Valve Open‖ and the ―Delay Valve Close‖ parameters (see screennumber 9).Please not that:• Each one of these parameters should be shorter than the ―Flushing Time‖ Parameter.• The addition of the time set for the ―Delay Valve Open‖ parameter with the time set for the ―Delay ValveClose‖ parameter should be shorter than the time set for the ―Flushing time‖ parameter.The following is a step by step description of the controller operation in installations that include a delay valve:1. A single screen or gravel media filter with a Delay valve:Starting the flushing cycle:• The same as in ―A single TAF filter‖ above.The flushing cycle:• Solenoid valve number 1 is switched on and the flushing of the filter starts.• The controller starts to counts down two parameters in parallel: The ―Flushing Time‖ parameter (seescreen number 5) and the ―Delay Valve Open‖ parameter (see screen number 9).• Once the ―Delay Valve Open‖ parameter is counted down to zero the Delay solenoid is switched on.• During the flushing process when the count down of the ―Flushing Time‖ reaches a value which is equalto the ―Delay Valve Close‖ parameter (see screen number 9) the controller switches off the Delay Valvesolenoid.• Once the ―Flushing Time‖ parameter is counted down to zero the solenoid is switched off and theflushing cycle ends.1.1 A single screen or gravel media filter with both Main and Delay valves:Starting the flushing cycle:• The same as in ―A single TAF filter‖ above.The flushing cycle:• The Main Valve solenoid is switched on and closes the filter’s downstream valve. The controller countsdown the ―Delay Main Valve Close‖ parameter (see screen number 8). Once this count reaches zero theprocess moves to the next stage.• Solenoid valve number 1 is switched on and the flushing of the filter starts.37

• The controller starts to counts down two parameters in parallel: The ―Flushing Time‖ parameter (seescreen number 5) and the ―Delay Valve Open‖ parameter (see screen number 9).• Once the ―Delay Valve Open‖ parameter is counted down to zero the Delay solenoid is switched on.• During the flushing process when the count down of the ―Flushing Time‖ reaches a value which is equalto the ―Delay Valve Close‖ parameter (see screen number 9) the controller switches off the Delay Valvesolenoid.• Once the ―Flushing Time‖ parameter is counted down to zero the filter solenoid is switched off and theprocess moves to the next stage.• The controller counts down the ―Delay Main Valve Open‖ parameter (see screen number 8). Once this countreaches zero the Main Valve solenoid is switched off causing the downstream valve to reopen and theflushing cycle ends.2. A battery of screen or gravel media filters with a Delay Valve:Starting the flushing cycle:• The same as in ―A single TAF filter‖ above.The flushing cycle:• Solenoid valve number 1 is switched on and the flushing of the first filter of the battery starts.• The controller starts to counts down two parameters in parallel: The ―Flushing Time‖ parameter (seescreen number 5) and the ―Delay Valve Open‖ parameter (see screen number 9).• Once the ―Delay Valve Open‖ parameter is counted down to zero the Delay solenoid is switched on.• Once the Flushing Time parameter is counted down to zero the solenoid of the first filter is switched offand the process moves to the next stage.• The controller counts down the ―Between Filters Delay‖ parameter (see screen number 5) and once thiscount reaches zero the controller switches on the solenoid of the second filter of the battery and startsto count down again the Flushing Time parameter. Once the flushing process of the second filter isfinished the controller counts again the delay between filters and starts the flushing of the next filter.This process continues till the last filter starts to flush, then the process moves to the next stage.• During the flushing process of the last filter of the battery and when the count down of the ―FlushingTime‖ reaches a value which is equal to the ―Delay Valve Close‖ parameter (see screen number 9) thecontroller switches off the Delay Valve solenoid.• Once the ―Flushing Time‖ parameter of the last filter is counted down to zero the filter solenoid isswitched off and the flushing cycle ends.2.1 A battery of screen or gravel media filters with both Main and Delay valves:Starting the flushing cycle:• The same as in ―A single TAF filter‖ above.38

The flushing cycle:• The Main Valve solenoid is switched on and closes the battery’s Main Valve. The controller countsdown the ―Delay Main Valve Close‖ parameter (see screen number 8). Once this count reaches zero theprocess moves to the next stage.• Solenoid valve number 1 is switched on and the flushing of the first filter of the battery starts.• The controller starts to counts down two parameters in parallel: The ―Flushing Time‖ parameter (seescreen number 5) and the ―Delay Valve Open‖ parameter (see screen number 9).• Once the ―Delay Valve Open‖ parameter is counted down to zero the Delay solenoid is switched on.• Once the Flushing Time parameter is counted down to zero the solenoid of the first filter is switched offand the process moves to the next stage.• The controller counts down the ―Between Filters Delay‖ parameter (see screen number 5) and once thiscount reaches zero the controller switches on the solenoid of the second filter of the battery and startsto count down again the Flushing Time parameter. Once the flushing process of the second filter isfinished the controller counts again the delay between filters and starts the flushing of the next filter.This process continues till the last filter starts to flush, then the process moves to the next stage.• During the flushing process of the last filter of the battery and when the count down of the ―FlushingTime‖ reaches a value which is equal to the ―Delay Valve Close‖ parameter (see screen number 9) thecontroller switches off the Delay Valve solenoid.• Once the ―Flushing Time‖ parameter of the last filter is counted down to zero the filter solenoid isswitched off and the process moves to the next stage• The controller counts down the ―Delay Main Valve Open‖ parameter (see screen number 8). Once this countreaches zero the Main Valve solenoid is switched off causing the Main Valve to reopen and the flushingcycle ends.39
